e-motion Remote Shield v2

UPDATED VERSION: I've made a number of changes to make the shield more robust. The shield itself is thicker, and there is extra space between the remote case and parts of the shield--which had been in contact and could result in the shield breaking if the screws are tightened too much. Fixed these things, along with a few other minor model tweaks.

This is a shield for the Alber e-motion remote control ("cruse control"). The Alber e-motion wheels are built to fit on standard wheelchairs, and provide power-assist mobility for wheelchair users. The Remote is a Bluetooth-connected device that allows hands-free speed control for navigating up and down inclines or over longer distances. The remote has a large knob that spins continuously--CW for faster speeds, CCW for slower. One drawback of this design is that it is easy to bump into the knob and thus start moving, or speed up, by accident. This shield covers part of the knob so that it is less likely to be brushed against--but the knob is still easily reached so no functionality is lost.

To install this shield, pull up the rubber cover and remove the three screws from the back of the remote unit and carefully remove cover and metal rear plate. Keep those in a safe place in case you need them in the future. Using the same three screws, attach the shield where the metal plate used to be. Be careful to ensure the USB charging jack is clear in the slot on the back of the shield and that the shield sits flat in the remote case. Tighten the screws, but don't over tighten. The slot for the USB connector is large enough to accept most USB charging cables.

I suggest printing this model in PLA, using PETG or the Bambu Support Material for the support. For strength, the profile prints the entire model as a solid, with 100% fill. After printing, check that the model holds together and doesn't break apart or de-laminate with flexing. Strength is important here. PLA is quite strong in this regard, but some other materials may not adhere to itself quite as well. Do not use the shield if it is cracking or splitting apart. In that case, reprint the model--making sure your filament is dry and good quality.

Important note: I am in no way associated with Alber, or any other mobility provider, other than as a user of these products. I am not responsible for any damage you may incur when modifying your Remote, or any issues you may experience in using this shield. As with all mobility devices, use care in their use.
