  In this paper, we investigate the effect of the Generalized Uncertainty
Principle (GUP) in the Casimir wormhole spacetime recently proposed by
Garattini [Eur. Phys. J. C (2019) 79: 951]. In particular, we consider three
types of the GUP relations, firstly the Kempf, Mangano and Mann (KMM) model,
secondly the Detournay, Gabriel and Spindel (DGS) model, and finally the so
called type II model for GUP principle. To this end, we consider three specific
models of the redshift function along with two different EoS of state given by
$\mathcal{P}_r(r)=\omega_r(r) \rho(r)$ along with $\mathcal{P}_t(r)=\omega_t
(r)\mathcal{P}_r(r)$ and obtain a class of asymptotically flat wormhole
solutions supported by Casimir energy under the effect of GUP. Furthermore we
check the null, weak, and strong condition at the wormhole throat with a radius
$r_0$, and show that in general the classical energy condition are violated by
some arbitrary quantity at the wormhole throat. Importantly, we examine the
wormhole geometry with semi-classical corrections via embedding diagrams. We
also consider the ADM mass of the wormhole, the volume integral quantifier to
calculate the amount of the exotic matter near the wormhole throat, and the
deflection angle of light.
