Toggle Clamp

A toggle clamp that I developed to easily open and close a 2-part pipe adapter

This was a project-integrated model for which I added a base plate and an alignment jig for this purpose

Assembly:

• prepare both base plates, the spacer template, and mounting screws (tools for the screws, of course)
• screw on one of the two base plates
• place the template against the mounted base plate and now insert the other base plate flush into the other recess
• now screw down the second base plate and then remove the template
• now complete the clamp with the remaining parts
• insert the lever and push in the longer shaft
• insert the bail and push in the shorter shaft
• put a little superglue into the end caps (only lightly moisten the inside and do not fill)
• attach the end caps and press firmly onto the shaft (clamp grip shaft and cap) both must sit flush
• Finished

! 0.12mm layer profiles have a second build plate with a modified model with flush-fitting countersunk shafts!
Only attach the end cap of the shafts to the part once you have assembled the clamp. Otherwise, you will hardly be able to remove the shaft again

+ 0.2mm PLA Compact version (12.05.2026)

+ 0.2mm PLA extremely Compact version (15.05.2026)

+ 0.2mm ASA Compact version (15.05.2026)

I developed the toggle clamp for ASA material. (ABS should also work well) (PLA profile added)

Shafts are fixed with the cap after insertion ( a little superglue in the cap please)

But please screw it on first. otherwise, a fastener will be covered.

Alternatively, M4 screws of 24mm and 30mm length can be used (longer is always possible, of course),

but here you should not overtighten and use threadlocker or self-locking nuts

The template is designed for a tension of 2mm

Dimensions of the normal version (mounting surface only): 78 (71) x 32 (26) x 22.3mm

Printing:

ASA print profile is with raft for critical components. (Parts with a small contact surface or greater height)

Print profile is with scaling for ASA. (x=101%, y=101%, z=100.7%)

ASA tested without raft, but with strong warping on the bail and slightly on the counter-holder. Thus, not recommended.

PLA print profile added without raft and without scaling. (tested in PLA Silk+ Candy Green)

Possible post-processing:

depending on printer calibration, the shafts can be quite tight with a 0.2mm layer profile

scratching a bit with a knife over the layers of the shafts may be enough

Please also give me feedback on how it fits for you

planned, in testing and results: (updated: 13.06.2026)

• Print model for PLA without raft and scaling (test running 02.05.2026) / profile added (02.06.2026)
• Test in ABS without raft - tested / too much warping and please print only with raft (03.06.2026)
• Compact version created / ASA profile added (03.05.2026)
  / PLA profile added (08.05.2026)
• Equip counter piece and clamping bail with a notch for centering when clamping. / ASA profile added (03.05.2026)
  / PLA profile added (08.05.2026)
• ultra compact version created / PLA profile added (08.05.2026)
• Add ABS / ASA profiles (10.05.2026)
• Add 0.12mm layer versions, for finer finish and smoother-to-insert shafts (PLA profiles online 11.05.2026)
• Countersunk shafts with end piece and adapted holder/lever with countersunk holes (0.12mm PLA versions online 11.05.2026)
• Partially adjust the support distances for 0.2mm versions (11.05.2026) / Compact version adjusted (12.05.2026)
• Reduce the minimum layer time for 0.2mm versions again (11.05.2026) / Compact version adjusted (12.05.2026)
• I will additionally optimize the normal version for 4mm screws (13.06.2026)
